Derived Service and EndpointSlice is created at member cluster, not parent cluster

[zjzhangkui]

I follow this document(https://clusternet.io/docs/tutorials/mutil-cluster-service/visting-services-in-child-cluster/ ) to enalbe MultiClusterService, the serviceimport is created at parent cluster, not at member cluster, there is no Derived Service and EndpointSlice created at member cluster. however, the Derived Service shoud be accessd at member cluster.

@zjzhangkui Please check whether ServiceExport exists in child clusters. Also please check the logs of clusternet-agent and find out some suspicious error traces.

cc @lmxia Please take a look. Thanks.

As expected, Derived Service should be created at parent cluster rather NOT member cluster. Sorry i did't really get the error messages. Could you please give us more further info ?

@lmxia If Derived Service is create at parent cluster, how to access the service by service name for application deployed at member cluster? the parent cluste is controll cluster, and applications is deployed at member cluster.

Does clusternet-controller-manager will create serviceimport at all child clusters which has serviceexport created? If not, the crd of service import created at child cluster for what?

That is a good question,for now we only support north-south service traffic from parent cluster and this feature has a pre-condition: parent cluster can visit child clusters pod CIDR directly. Surely it's limited and tasteless, so we provide a sulotion to integrate with submariner. , and keep Clusternet mainly focus on application and cluster management.

As you said, submariner will handle and sync serviceimports accross clusters.
